Plants and Water Temperature

Problem Scenario

I am trying to find out if it is better to water a plant with hot or cold water.

Broad Question

Wich one makes a plant grow faster, hot or cold water?

Specific Question

How does the temperature of water impact the growth of a plant?

Hypothesis

The cold water will make the plant grow faster.

Graph of Hypothesis

Variables

Independent Variable: Temperature of Water

Dependent Variable: Speed of Growth

Variables That Need To Be Controlled: The amount of water, the cup I use, the type of plant etc. etc.

Vocabulary List That Needs Explanation

Temperature : a measure of the warmth or coldness of an object or substance with reference to some standard value. The temperature of two systems is the same when the systems are in thermal equilbrium.

General Plan

• Where will you conduct this experiment? If not at school where are you going to put your experiment so that it doesn't bother anyone, you can assure it won't be disrupted by pets or babies, and it will be safe from changes in temperature or movement? - I am going to this experiment at my house.
• What will you actually be doing? For example, measuring something, timing something... - I am going to measure how fast a plant grows when you give it a different temperature of water.
• What are some potential problems you may encounter and how will you solve them? - They will probably die, but then I will have to start over.
• What are the safety and environmental concerns? - I will have them blocked off from any pets, babys, or any potential harm.

Potential Problems And Solutions

If they die, I will start over with a shorter amount of time.

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
Sun Flower Seeds	1 pack	Mr. Groves	$0.00
Recycled Pots	2	Home	$0.00

Detailed Procedure

1. I'm going to put two plants down by a window sill so that they can both get sun.
2. I'm going to water them on every Wednesday one will be watered with cold water, and the other with hot.
3. I will wait for them to grow, and observe which one will grow faster.
